Indlela yokukhetha ubushushu bokucofa kwe ukuchithwa kwesithando somlilo?

Xa unyibilika i-alloy, ukuba iqulethe i-molybdenum okanye i-tungsten alloy, ukushisa okuthephayo kufuneka kulawulwe kwi-1650-1700 ℃; kwimanganese, ubushushu bokucofa kufuneka bulawuleke kwi-1600-1620℃. Ukongeza ekuqinisekiseni i-alloy etyhidiweyo, xa unyibilika i-ingot okanye ezinye izinto ezibuyiswayo ezibuyiswayo, ukushisa okuthephayo kunqunywe ngokuhambelana nokubunjwa kwensimbi etyhidiweyo kwisithando somlilo.
